    If you buy a MBP with Lion and it connects to the Internet for an install, will it automatically change to Mountain Lion after you purchase ML in a few months? Meaning it will create a new partition?

    Or if you do a fresh install, do you have to install Lion first and then go through the App Store and install Mountain Lion?

    No, you would have to download and install ML.
    You don't have to re-install Lion. Just go to the Mac App Store and upgrade to ML.

    When you buy ML (assuming it works exactly the same as Lion) you'll download an installer through the app store. You then run the installer and it'll upgrade Lion to ML, leaving all your files and apps where they are. If you want it on a partition you'll have to specifically create one through disk utility then select that drive when installing ML.

    I'm not sure if you can say wipe everything then install a new ML. I usually do a fresh install in a different partition, then when I have that all set up I delete the previous partition and move the new one over.
